B B1 are pulleys mounted securely in the frame K K. A A are ropes, or cords, four in number, one of said ropes being secured to each icorncr of a swinging table or platform F, preferably perforated, as shown. in the top of said frame K K is a cylinder D, having a piston-head a and piston-rod- 12 adapted to reciprocatetherein.

Connected to the free end of the piston-rod- -b is a set of independently-mounted pulleys G', said pulleys being adapted to slide back and forth upon the frame K K, J is asec- 0nd set of pulleys mounted stationary in the frame K K. H is afeed pipe connected to a source of fluid-pressure supply communicating with the rear end of said cylinder D, the

This platform or table F is preferably composed of a framework of rods f, interwoven with wire f upon which is-laid a perforated rubber cover f When a cover and platform ofv this character are used; the draining of water from the same is very rapid, anotheradvantage being that the water is allowed to flow up through the platform while being lowered into the tub.

This apparatus is generally used in hos pita'ls and the like for removing very ill patients from the bed to the bath-tub and back again without subjecting themto any exertion: Therefore the tub or other device upon which the applianceis mounted is genorally provided tu'b to be drawnup beside the bed or the like.

This appliance may also 'be employed for: v transferring. patients from an operating-table to a bed or from'bne -bedto another,

as will begbvious.

he valve-X,ncontrolling the inlet and outi let of water to the tub, is carried by the tub,

= to-which a hose might be connected for fill;

ing the tub, the water being allowed to run directly intoa sewer in emptying the tub. While: I have illustrated and described my I apparatus as attached to an ordinary tub pro,-'

:vided with rollers and adapted to be operated 1 the same by fluid-pressure, it is obvious-that may be operated in any suitable ,manner,

such as by electricity and the like. It is also obvious that many changes might bemade in my said invention without departing from the 330 ed above said tub or receptacle, pulleys carspirit thereof and that the details thereof may be altered to suit varying requirements. U

Having thus described my. said invention,

what I claim, and desire tosecureby Letters Patent of. the United States, 'is-;
